Answer:
Synthesis Reaction
General Formulas and Concepts:
<u>Chemistry - Reactions</u>
- Synthesis Reactions: A + B → AB
- Decomposition Reactions: AB → A + B
- Single-Replacement Reactions: A + BC → AB + C
- Double-Replacement Reactions: AB + CD → AD + BC
Explanation:
<u>Step 1: Define</u>
RxN: 2Na + I₂ → 2NaI
<u>Step 2: Identify</u>
2Na + I₂ → 2NaI
A + B → AB
Synthesis Reaction
Answer:
the motion of atoms decrease when there is a decrease in velocity and kinetic energy that is decrease in temperature. this occurs during freezing and condensation.
Explanation:
Answer:
The moles of gas is 0.009474 moles.
Explanation:
Given that,
Volume = 526 mL
Pressure = 346 mmHg
Temperature = 35.0°C
We need to calculate the moles of gas
Using formula of ideal gas

Where, P = pressure
V = volume
R = gas constant
T = temperature
Put the value into the formula


Hence, The moles of gas is 0.009474 moles.
100000 Cubic Millimetres is the answer
D=m/V=0.72/0.1x0.08x0.02=4500(kg/m3)
